At the same time, more and more people are into outdoor extreme sports, such as rock climbing, etc. The indoor sports or the outdoor sports are attractive for people as they can train the body, release stress, and keep people more healthy and happy.

Nowadays, there are many kinds of fitness equipment or facilities for the pull-ups, which are relatively simple, refer to the structure shown in FIG. 1 and FIG. 2 in the Attached Figures of Specification, and a crossbar is supported by the bracket to a certain height, and the human body can do pull-ups by gripping the crossbar;

Each of our fingers except the thumb generally has three sections. In this application, the section that is connected to the palm is called the first knuckle, the middle section is called the second knuckle, and the outermost section is the third knuckle. As shown in FIG. 1 and FIG. 2, when we exercise with the pull-up device, the palm grasps the crossbar, and the arm strength, muscle strength between the first knuckle and the palm can be trained, the second knuckle and the third knuckle are mainly used as an auxiliary grip function, and their exercise effect on the grip force is not strong;

Existing pull-up devices are unable to provide adequate exercise for the muscle connecting the third knuckle and the second knuckle, and the muscle connecting the second knuckle and the first knuckle; and the muscles of the said knuckles is the key of gripping exercise and is a very important physical element in sports such as rock climbing.

To sum up, based on the existing technology, either the pull-up fitness equipment shown in FIG. 1 and FIG. 2, or other existing fitness equipment for the pull-ups are only for exercise of the muscle strength of the arm.—arm strength, and slightly exercise the grip of the first knuckle and the palm, but the strength of the second knuckle and the third knuckle muscle of the finger is not trained specifically; and some extreme sports such as rock climbing, not only require strong arm strength, but also strong grip force of the fingers, and these even related to the safety of climbing. Therefore, it is very necessary to design a pull-up device capable of training finger grip force to be used for the safety grip force exercise of climbers and fitness enthusiasts. It will be also very marketable.
